Had someone gone with indimail. They had modified the qmail for better and faster delivery.
http://indimail.sourceforge.net/ I'm not here to show advantage or benefits of other mail server on the list, but as a old user of qmailtoaster how can we upgrade our toaster with the new features. It also has many features like preventing outgoing mail from different domain with authentication from domain on server (just like gmail) and many other features. Eric, As a new leader of qmailtoaster, I would appreciate if you check out with new upgrades and features to qmailtoaster. I had been very less active on list from last few months, but I never missed to read mails whenever I get time and post. I'm ready to help whatever possible from my side. Amit Dalia
